Enjoy the free chest and
x-rays.
Better get that HV under control.
This leads me to the following report.
ALL of the resistors in the HV regulator circuit were waaaay off. Changed them all out with some 1% resistors as seen in the picture.
The focus resistors were even worse. 22M was like 43M. All were replaced with series-parallel 1%'ers to make up the high resistance and wattage values.
Caps in the HVR and the defective burned one were replaced as well.
After futzing around with why the width was shrunken. The 6DQ5 was replaced a few days ago by the owner. He reports full width and 710V of boost.
I placed an additional type AGC fuse & fuseholder in the existing holes in the top of the chassis. Changed out both the type N fuse & fuseholder for AGC. Now both the primary and secondary is fused.
This weekends adventure is fixing the vertical linearity. Everything
has been replaced EXCEPT for the components in the yoke.
So I'm go'in all in.
Enjoy some pix.
